k line diesel locomotive

Description

I have a k line diesel switcher locomotive for sale, it has two motors, all wheel drive system, everything works, it is ac transformer driven, but sometimes it jumps track, and it is missing the horn in top. I'm not sure if it is the tracks, or if it is something with the locomotive itself, because all of my other trains jump the same track, so I'm guessing it is just my tracks. Other than that everything works well. It will need a good cleaning, but other than that it works great. This is a sold as is item, being as it is used, there are imperfections, but small ones.
